Microsoft’s rolling out its new Outlook Premium service, which lets you hook the service into your own domain and offers up that email account ad-free.

The premium tier allows you to use Outlook with custom domains, like joe@pizzaisgreat.pizza. You can create up to five email addresses per domain. If you don’t already own your own domain, Outlook can register that for you, but it’ll cost an extra $10/year after the first year. Everyone on that domain’s email system can share calendars, contacts, and documents, similar to how you would with a Google Apps account. The service is launching for a discounted rate of $19.95/year before bumping up to $49.99/year after March 31st.
